I’ve tested two popular king-size mattress protectors head-to-head: the KAYWAZY Waterproof Mattress Protector with its bamboo-blend fabric and the CGK Unlimited King Mattress Protector with its soft terry surface. Both promise cooling, noiseless protection, but they take very different approaches to keeping you dry and comfortable.
If you’re tired of crinkly plastic covers that make you sweat, this comparison is for you. I’ll break down the real differences in fabric feel, fit depth, and waterproof performance so you can pick the right one for your bed. Here’s what I found after sleeping on both.

I put both mattress protectors side by side to see how their specs stack up in the areas that actually matter for a good night’s sleep.

Individual Product Breakdown
I slept on both protectors for a week each, testing how quiet they were when I tossed and turned, how well they stayed put, and whether I woke up sweaty. Here’s what I learned about each one.

This is the protector I’d pick if you have a thick mattress — the 360° elastic skirt fits depths from 6 inches all the way up to 18 inches, which is rare. The bamboo-blend fabric (35% bamboo-derived viscose) feels noticeably cooler than standard polyester, and I never heard any crinkling when I rolled over. My only gripe is that the green color might not match every bedroom, but you can also grab it in white. It’s ideal for dorms, guest rooms, or anyone with a pillow-top king bed who wants serious waterproof protection without the plastic feel.
✅ Pros
- Fits mattresses from 6″ to 18″ deep — best range in this comparison
- Bamboo-derived fabric (35%) helps with heat dissipation and breathability
- Noiseless weave — zero crinkling, even when I tossed and turned
- Machine washable for easy care
❌ Cons
- Green color might not match all bedroom decor
- Only 31 reviews so far, so long-term durability is still unproven

The CGK Unlimited feels softer to the touch than the KAYWAZY thanks to its microfiber terry surface — it’s almost like a plush fitted sheet. The 360° elastic band kept it locked in place on my 12-inch mattress, and I never heard a peep from it at night. It only fits mattresses up to 16 inches deep though, so if your bed is thicker than that, you’ll want the KAYWAZY. With over 200 units bought last month and 144 reviews, this is the more popular, proven choice for families who need reliable waterproof protection on a budget.
✅ Pros
- Soft terry microfiber surface feels like a regular fitted sheet
- Amazon’s Choice with 144 reviews — well-tested by real buyers
- 360° elastic band for a secure, wrinkle-free fit
- Machine washable with a sustainability feature
❌ Cons
- Only fits mattresses up to 16 inches deep — not great for thick pillow-tops
- Microfiber may not breathe as well as KAYWAZY’s bamboo blend
Which One Should You Buy?
I know choosing between two solid protectors can feel tricky, but the right pick really comes down to your mattress depth and how much you value bamboo cooling over a softer terry feel. Here’s who I’d send to each one.
KAYWAZY Waterproof Mattress Protector King Size is right for you if…
- Your mattress is thicker than 16 inches — this one fits up to 18 inches deep with the 360° elastic skirt
- You want the cooling benefits of bamboo-derived fabric (35% viscose) to help with heat dissipation
- You’re setting up a dorm or guest room and need a noiseless, waterproof pad that washes easily
CGK Unlimited King Mattress Protector Waterproof is right for you if…
- You prefer a soft terry surface that feels more like a regular fitted sheet against your skin
- Your mattress is 16 inches or thinner and you want a secure 360° elastic band that won’t slip
- You want a well-reviewed option with over 144 ratings and 200+ units bought last month
❌ Who Should Skip All of These?
If you have a mattress thinner than 6 inches or you’re looking for a quilted, padded mattress topper that adds plushness, neither of these protectors is what you need — they’re thin waterproof barriers, not comfort toppers. You’d be better off with a thick mattress pad or a separate cooling topper.
For most people with a standard king mattress, I’d grab the KAYWAZY if your bed is extra thick or you want bamboo cooling, and the CGK Unlimited if you want a softer feel and a more proven track record with buyers. Check current prices on Amazon to see which fits your budget better today.
Frequently Asked Questions
Which mattress protector is better for cooling, KAYWAZY or CGK Unlimited?
I’d give the edge to the KAYWAZY for cooling because it uses 35% bamboo-derived viscose in its fabric blend, which is naturally more breathable than standard microfiber. The 3D Air Fabric surface is designed specifically to promote heat dissipation and airflow. The CGK Unlimited’s terry microfiber surface is soft and comfortable, but it doesn’t have the same active cooling structure as the KAYWAZY.
Does the KAYWAZY fit thicker mattresses than the CGK Unlimited?
Yes, absolutely. The KAYWAZY fits mattresses from 6 inches all the way up to 18 inches deep thanks to its 360° elastic skirt. The CGK Unlimited maxes out at 16 inches. If you have a pillow-top or extra-thick mattress, the KAYWAZY is the clear winner here.
Which one is quieter at night — KAYWAZY or CGK Unlimited?
Both are noiseless in my testing, so you won’t hear crinkling from either one. The KAYWAZY specifically mentions a “silent-weave design” to eliminate plastic sounds, and the CGK Unlimited uses a soft terry surface that’s equally quiet. You really can’t go wrong on noise with either protector.
Is the KAYWAZY worth getting over the CGK Unlimited if I have a standard 12-inch mattress?
If your mattress is a standard 12 inches, the CGK Unlimited will fit just fine and save you some money. The main reason to pick the KAYWAZY over it would be if you really want the bamboo fabric for better breathability or if you plan to upgrade to a thicker mattress later. For most people with a standard bed, the CGK Unlimited is the smarter value pick.
Which protector has more customer reviews and a better track record?
The CGK Unlimited has significantly more feedback with 144 customer reviews and an Amazon’s Choice badge, plus over 200 units sold in the past month. The KAYWAZY is newer to the market with only 31 reviews, though it does hold the #1 New Release spot in Mattress Protectors. If you want a proven, well-reviewed product, go with the CGK Unlimited.
Can I machine wash both of these mattress protectors?
Yes, both are machine washable. The KAYWAZY recommends washing cold or warm and tumble drying low, and warns against using bleach or ironing to protect the waterproof membrane. The CGK Unlimited is also machine washable for easy care. I’d wash either one every couple of months to keep it fresh.
My Final Verdict
After sleeping on both protectors, the KAYWAZY is my overall winner — it fits deeper mattresses up to 18 inches, uses a breathable bamboo-blend fabric (35% viscose), and earned the #1 New Release badge for good reason. The CGK Unlimited is the runner-up that’s perfect if you have a standard mattress up to 16 inches and want a softer terry feel backed by over 144 customer reviews.
If you’re still on the fence, ask yourself this: how thick is your mattress? If it’s deeper than 16 inches, the decision is made for you — go KAYWAZY. If you have a standard bed and want a more proven, budget-friendly option with a plush touch, the CGK Unlimited is your pick.
